FlashWizard Optical Slave Canon EX 3.5

$24.20 inc GST

Most optical slaves will not function properly with the popular Canon EX flash units — this optical slave will work with all Canon EX flash units. And, it utilizes the very reliable miniphone sync connector.
One very important requirement: the triggering flash must not emit a pre-flash as this will prematurely fire the connected flash. Therefore this optical slave does not support ETTL function.
The built in flash on Canon DSLR cameras CANNOT be used to trigger this optical slave as it always emits a pre-flash.
